THE purpose of the investigation here described was to ascertain whether the phospholipid content of the brain is a fixed amount, or an amount subject to changes of the hormone content of the brain tissue. The method used did not reveal any changes o

Cyclic adenosine 3′,5′-monophosphate (cyclic AMP) significantly increases the enzymatic activity of diphosphoinositide kinase. The attempts to identify the mechanism of action of cyclic AMP on diphosphoinositide kinase led to the observations tha

Summary1. The effect of amino acids, some polypeptides, and a few decomposition products on the synthesis of acetylcholine was investigated. 2. Most of the amino acids, carnosine, glutathione, and creatine increased the synthesis. 3. Glycine, leucine

1. 1. Release of catecholamines and their metabolites during activity and rest have been studied. Only small amounts of catecholamines (and metabolites) were released during rest. 2. 2. Catecholamine release and catabolism increased during hypothalam

Summary The in vivo effects of a glycoprotein fraction isolated by Lee (1974) on intracerebral impulse transmission have been studied. The results suggest that this substance fulfills the minimum necessary requirements of a “modulator” of noradre

Human spinal fluid is a more favorable medium to further the synthesis of acetylcholine in vitro, using enzyme obtained from frog brain, than is serum. Also, since less acetylcholine was synthesized in the presence of spinal fluid from patients with

ACCORDING to a recently presented concept,1much of the symptomatology in patients with myasthenia gravis can be explained by a decreased acetylcholine synthesis. Amino acids2and proteins3were found to increase the acetylcholine synthesis in vitro. It

1. The effect of cocaine, ergotamine and yohimbine on the activity of the phenol sulfur esterase has been investigated. 2. Cocaine inhibits the activity of this enzyme while ergotamine and yohimbine increase it. 3. This study suggests that the inacti
